Title: Improvements in or relating to holders for consumable elements
Inventor: ALLEN GORDON DAVIS
IPC: F16N15/00
Filed: 1958-10-23
Abstract: 874,102. Lubricating. ALLEN TOOL & ENGINEERING Ltd. Oct. 23, 1959 [Oct. 23, 1958], No. 33929/58. Class 12 (3). A spring-loaded holder for a solid lubricating rod has a base 1 having integral bearing mountings 2, 3, a guide-sleeve 4 slidably and rotatably mounted in the mounting 3, and an open-ended pusher-tube 5 slidably mounted in the sleeve 4. A compression spring 6 is retained in the tube 5 by a plug 7 secured to the sleeve 4 by the threaded ends of diametricallyopposed rods 8 which, along with lugs 9 attached to the mounting 2, carry tension springs 10. The sleeve 4 has diametrically-opposed slots 20, 21 and one end of the slot 20 opens into an aperture 22. The tube 5 has a resilient tongue 14 formed therein which has a detent 15 thereon. The detent comprises a boss 16 having a reduced diameter at 17 partly bevelled at 18, and the boss 17 is diametrically-opposite a threaded-hole 19 in the tube 5. The tube 5 is located in the sleeve 4 by a screw 23 in the hole 19 which is received by the slot 21 of the sleeve 4, and by the boss 17 engaging the slot 20 except at the position of retraction where the boss 16 is forced into the aperture 22 by the resilient tongue 14. The holder is moved to the loading position in two stages, firstly the sleeve 4 is retracted so that an integral lug 24 registers with a recess 25 in the base 1 and the sleeve 4 is then rotated so that a part 24a of the lug 24 is received by the recess 25 in order to lock the sleeve relatively to the base, and secondly the tube 5 is forced against the pressure of the spring 6 away from the mounting 2 until the boss 16 engages the aperture 22. The holder is then loaded with a solid lubricating- rod which is held in a recess 26 of the tube 5 and is guided by a bore 27 in the mounting 2. The rod is urged against the part to be lubricated by rotating the sleeve 4 so that it is free to move under the action of the springs 10. When the rod is sufficiently worn the bevelled part 18 of the detent 15 engages an edge 28 of the mounting 3 to depress the tongue 14 and so release the boss 16 from the aperture 22 and allow the action of the springs 10 to be supplemented by the spring 6. The rods may be composed of a graphite mixture encased in a harder carbon tube or of molybdenum disulphide in a synthetic plastic carrier.

Title: Electrical hot water generator
IPC: F24H1/10
Filed: 1953-12-11
Abstract: 761,254. Electric water heaters. STIEBEL, T. H. Dec. 11, 1953, No. 34559/53. Class 39(3) [Also in Group XXIX] A water heater for a spray has means for maintaining the volume and temperature of the emitted water substantially constant and includes pressure sensitive bellows 9 of which the vertically movable bottom 11 has soldered to it a control rod 14 having screwed on its lower end a conical plug 22 which is adapted to register with a water inlet conical bore 21. The rod 14 is also connected, at its top end, by means of a forked member 27 and a pivoted U-shaped member 28, to a mercury switch 33 which controls current supply to an electric heating element 2 coiled in a compartment 3 between an outer container 1 and an inner container 4. A water supply fitting 24 having an inlet valve controlled by a handle 57 is connected to the bottom of the container 1, and and outlet pipe 41 is connected to a spray head 50 via an emission faucet 44. Upon opening'the inlet valve, water flows into the bottom of the compartment 3 through the conical bore 21 and after filling the compartment flows out through the pipe 41. If the emission faucet 44 is first adjusted to pass less water than the inlet valve, pressure produced in the compartment 3 causes the bottom 11 of the bellows to move upwardly against the action of a spring 12, and the switch 33 closes, the plug 22 simultaneously moving upwardly to partially close the bore 21. The dimensions of the plug and bore 22, 21 are such that if the pressure is maintained within the compartment 3 by appropriate adjustment of the emission faucet 44, the volume of inflowing water is kept constant independent of the mains water pressure. Supplementary water outlet control is provided by varying the degree of registration of two bores in the emission faucet. A sleeve slidable in a perforated cylinder may permit control of the water supply in place of the conical plug and bore (Fig. 6, not shown). In an additional feature, Fig. 8, an iris shutter 75 is controllable by a bimetal strip 74 which, if for any reason the temperature of the emitted water should rise, bends and opens the shutter wider thus allowing more water to pass and lowering the output temperature of the water once more: A lamp 36 is connected in parallel with the heating element.

Title: Cross-linked diisocyanate-modified polyesters of high molecular weight and process for producing same
IPC: C08G18/66
Filed: 1954-11-30
Abstract: An intermediate for the production of diisocyanate-modified polyester rubbers is prepared by reacting a mixture of a polyester containing hydroxy groups and a glycol with a diisocyanate in amount sufficient to produce a product containing free hydroxy groups.  This product is stable and may be transformed into a rubber by heating with additional diisocyanate during and/or after moulding.  The diisocyanate may first be incorporated into the intermediate on rolls without cross-linking taking place.  The polyesters should be substantially linear, saturated and aliphatic and may in part be derived from diamines and aminoalcohols.  Suitable glycols to be used in admixture with the polyesters are butylene glycol, diglycol, thiodiglycol, hexanediol, urea glycols, urethane glycols, e.g. the reaction product of 2 mols. butylene glycol and 1 mol. hexamethylene diisocyanate, amide glycols, quinitol and glycols containing ester groups.  Usually 1-10 per cent of the glycol by weight of the polyester is used.  The intermediate is soluble in glycol monomethylether acetate and can be sheeted on rolls.  Diphenyl methane diisocyanate is preferably used in the cross-linking reaction in an amount 5-10 per cent by weight of the intermediate.  Three examples are given using glycol adipic acid polyesters, butylene glycol or quinitol as the added glycol, p-phenylene diisocyanate or 1.5-naphthalene diisocyanate in the first stage and diphenyl-methane diisocyanate in the cross - linking stage.  Physical properties of the final products are tabulated.  Specifications 700,608, 755,779 and 760,140 are referred to.
